In the drawings accompanying this specificationand'forming a part thereof 1 have shown, for purposes of illustration,one form whlch my invention may assume. In these drawings: I

In the drawings I have shown a plate 11 adapted to be heated andprovided w1th a plurality of pins 12 similar to the p ns in a heel mold,each adapted to recelve a washer 13, and recessed at 15 to provide acavity beneath the washer 13. After the washers are all in position onthe pins 12 the heel blank M is placed upon the pins in proper relationthereto and pressed 1nto firm engagement with the washers 13 as shown inFigures 2 and 4E whereupon stock of the blank 14 is softened by the heatof the pins 12 and flows through the apertures or" the washers 13 intothe cavities 15 to form rivets 16 uniting the washers 12 to the blank14. After this the blank 14: is removed from the pins 12 carrying withit, because of the adhesive surface of the heated blank 14; and becauseof the rivets 16, the washers 13. When the mold has been removed fromthe press and the cured heels removed from the mold the heel blanks 1dcarrying the Washers 13 are placed directly into the mold without showsthe heel carrying the an '1- shows in detail a washer receiv- 12,1922;Serial No, 594,099..

Variousdetails inthe apparatus herein shown may be varied withoutdeparting from. my inventionwand thisdisclosure is,

in fact, illustrative only so that my invention isnot lim-ited thereto.

I. claim:

1." The method for" positioning washers on the washer pins of amoldp'r'ior to the mold in'g operation which-comprises pressing thewashers in a; heated F condition against the rubber heel blank in properpositionsto encircle the pins when the blank is thereafter placed in themold cavity.

2. The method of inserting washers in a rubber heel which comprisessecuring the washers by the application of heat to the heel blank priorto the insertion of the latter in the mold and applying the blank to themold cavity in such manner that the washers encircle the pinsthereof.

3. The method of applying substantially flat washers to the surface of aheel blank prior to the inserting of the latter in the molds whichcomprises applying the washers toproperly spaced heated pins and thenapplying the heel blank to said pins.

4. The method of applying washers to a rubber heel blank prior to itsinsertion in the mold which comprises softening the blank and forcingthe Washers in desired positional relation against the surface of theblank.

5. The method of applying washers to a rubber heel blank which comprisessoftening the blank by the application of heat and forcing the washersin desired positional relation against the blank, prior to its insertionin the mold.

6. The method of securing washers in desired position in a rubber heelblank prior to its insertion in the mold which comprises positioning thewashers on a heated support bringing the blank into contact with the sopositioned washers and applying pressure suflicient to partially imbedthe washers in the blank. e

7. The method of securing apertured' washers in desired position in arubber heel blank prior to its insertion in the mold which comprisespositioning the washers on a heated support, bringing the blank intocontact With the so positioned Washers and applying pressure sufficientto force a portion of the rubber through the apertures of the Washers.

8. The method of inserting a Washer in a rubber heel which comprises,positioning the Washer on aheated pin, bringing the heel in anunvulcanized position into contact with the so positioned Washer,whereby the rubber at the point of contact is softened and the Washersecured thereto, removing the heel and attached Washer from the pin, andthen molding and vulcanizing the heel.

9. That improvement in the process of manufacturing rubber heels havingnail receiving Washers embedded therein, Which consists in securing theWashers in a rubber heel blank in substantially the positionalrelationship Which it is desired to have them bear to each other in thefinished heel, by

heating the blank at the points Where the Washers are applied,subsequently placing said blank in a heel mold, and then performing themolding and vulcanizing operations on the blank While holding saidWashers in said relationship.

10. That improvement in the process of manufacturing rubber heels havingfastener receiving Washers embedded therein, Which consists in fixingthe fastener receiving Washers to the surface of a substantiallyunvulcanized rubber heel blank in substantially the positionalrelationship Which it is desired to have them bear to each other in thefinished heel, by softening the blank at the points Where the Washersare applied, and then molding said blank in the usual manner.

ll.'That improvement in the process of manufacturing rubber heels havingfastener receiving ashers embedded therein, which consists in fixing thefastener receiving washers to the surface of a substantially unvulcanized rubber heel blank in substantiall the positional relationshipWhich it is de sired to have them bear to each other in the finishedheel by the application of'heat and then molding said blank in the usualmanner.

In testimony whereof I have signed my name to the above specification.
